3 C'laims.

This invention relates to the pumping of water or other liquids from below-ground to the surface, or one level to another, and is adapted for use with a pressure tank, not shown, pipe line or open tank.

The objects of this invention are as follows:

First: to relieve the lifting stroke from all pressure, resulting in a simple gravity lift even where a pressure tank is used.

Second: to utilize, for working purpose, the gravity force produced by the weight of the falling pump-rod on the down stroke.

Third: to provide hydraulic means which eliminate the jarring shock of the reciprocating action.

Fourth: to prevent the waterlogging of the tank in a pressure system.

Fifth: to make more eflicient use of the power applied.

These objects are accomplished by the use of a balancing cylinder on Vthe pump, and the combination upon the pump rod of a plunger fixed to the rod with a valvular device mounted movably upon the rod below the plunger, together with accessory devices associated With said valvular device. There is included an intermediate delivery conduit to receive and deliver a stream of water or other liquid during the operation of the pump, Whereby the pump rod when descending may utilize its own gravity for facilitating the operation of the pumping stro-ke, also relieving the cylinder located in the well from all pressure duty.

The above considerations thus enhance the utility of the pump, and effect a saving of power resulting from the smoother action of its elements.

In the drawing, Fig. 1 is a side elevation of my improved pumping device, with parts removed or cut away. Fig. 2 is a longitudinal axial section of Fig. 1. Fig. 2'a is an enlarged longitudinal central section lower valve.

The numeral l denotes the barrel or casing of the upper part'of the pump, the casing I having a cap 3 threaded removably thereon and somewhat contracted at its upper end, with the upper end threaded to receive a centrally apertured bearing.

A plunger rod IB traverses the bearing 4 for reciprocaton therethrough, the rod being broken away above the hearing 4, but it will be understood that any appropriate means may be connectedoperatively to said rod for actuating it. The cap 3 may have an outlet tube 5, threaded horizontally thereinto laterally, and said tube 5 has an outward thread to seat thereon an anglespout B, which may be turned up or down as desired to prime,'or drain, in case of damage to packings.

The cylindrical body l has a member 1 inwardly threaded to seat it upon an external thread on the lower outer wall of said body, and said member has at its lower and outwardly directed flange with opposite upwardly directed and interiorly threaded studs to seat the cap screws |5 therethrough, to project downwardly therefrom.

The numeral 8- denotes a downwardly extending member of the pump body positioned below and spaced from the member 'I and having an out- Ward rim, said rim having interiorly threaded opposite holes to seat therethrough the screws l5 which also traverse downwardly directed bosses on the rim. The numeral |2 (see Fig. 1) denotes a rubber sheet clamped between the body part 8 and the flange 1 to prevent leakage.

Within the hollow 8a. is a bell-Shaped valve cage 23 surrounding the pump rod 22, with openable lower end, and the lower end face is narrowed without to seat around it a conical packing ring 25.

The inner face of the lower part of the cage member is threaded to receive within it, valve seat 24 with its lower part widened to support the packing ring 25. The lower body 8 has a thickened wall.

Within the valve cage 23 is a metal valve 21, which surround-s pump rod 22. and is loosely positioned upon the top of valve seat 24. Valve 21 has at its upper end an outwardly widened shoulder resting upon a composition ring 26.

The upper face of member 21 has a concentric hollow in Which is an annular ring 28 with vertical side wall inturned. Fig. 2a is an enlarged representation of the member 21 with the ring 28 therein, which has an upwardly directed side wall inturned at the top. A composition ring with upwardly directed outer wall 29 is fitted within the member 28 and secured by the inturned part thereof, and the ring also has an upturned inner ring 29a and is pressed into valve 21.

Due to the action of packing ring 29 to hug pump rod 22 on upstroke it will rise to top of valve cage 23, allowing liquid to fill vacuum chamber 22a. On the down stroke, valve 21 will move with pump rod till ring 26 rests on valve seat 24, thus preventing any pressure on well pi-pe or lower cylinder, and discharges contents through passage 8f, The packing ring 26 is held in place by a looking ring 26a, resiliently. As shown in Fig. 2 the ring 25 packs against the lower end of the member 23.

A bushing 9 has an inner threaded connection with the threaded upper end of the well pipe IO, shown cut away, but it is directed downwardly into a source of liquid content.

Referring to Fig. 2, the chambered part 8 has a lateral passage 8]z into a second Chamber 8e in an extended or widened part, and an exteriorly threaded plug 13 With concaved top I Sa, is fitted in the apertured bottom of the chamber Bb with interior hollow 8e, which hollow at the top is narrowed, slightly, to register with openings 8d, llb, and 'la in casting 1, which seats the lower end of a street ell therein. Outlets can be taken off from |4 or |3 or both, thus making possible to have a fresh water outlet in connection with a pressure system.

The upper end 2|a of the pump rod 22 is threaded around the part having an interior thread, and is seated in a hollow seat in plunger ll, which is threaded on plunger rod IG. This in turn makes a swivel seat 2l for the pump rod. One or more packing cups are fitted slidably within the liner tube 2, which latter eXtends downwardly from within the tubular body I and cap 3, to terminate below at part Ha. The upper part of plunger I'I being widened outwardly to compress the inturned upper end of the packing cup IG, an externally channelled spacer member l9, is placed above packing cup 2| and bushing 241, and is threaded on to plunger I'I to produce a tight seal to prevent leakage,

Channelled member IB and bushing on the Suction stroke will allow the packing cups to collapse and a small amount of air to pass by and enter the liquid being pumped, which prevents a waterlogged pressure tank. When bushing 9 is removed with a two inch pipe in well, and a fiush cap cylinder by removing cap 3 entire, work parts IS, ll, and valve cage 23 can be removed or installed without disturbing other parts in any way.
